BURNS D. LOCKWOOD, 0F BELLEVUE, PENNSYLVANIA, ASSIGNOR TO PRESSED STEELCAB COMPANY, OF PITTSBURGH, PENNSYLVANIA, A CORPORATION OF NEW JERSEY.

CAB-TRUCK.

Application filed December 24, 1915.

To all whom it may concern:

Be it known that I, BURNS D. L oKwooD, a citizen of the United States,residing at No. 366 Lincoln avenue, B'ellevue, in the county ofAllegheny and State of Pennsylvania, have invented certain new anduseful Improvements in Car-Trucks, of which the following is aspecification.

An object of the present invention is to provide improvements in what isknown to railway engineers as the Fox type of truck for railway rollingstock, or in trucks of similar type, and particularly to increase thestrength of the truck without increasing its size or materially changingits proportions.

Railway cars have increased in capacity from, say 60,000 lbs. in 1900 to120,000 lbs. or more, in 1915, but little attention has been given tothe strengthening of the Fox. type of truck, the same having been usedpractically without change in construction notwithstanding such increasein car capacity, one of the reasons therefor being that the side framesof these trucks are formed by pressing sheet metal to shape in expensivedies and an increase in the size or proportions of such trucks wouldrender such dies useless.

An example of the Fox type of freight car truck is illustrated in UnitedStates Patent No. 468,146, granted to D. L. Barnes,

February 2nd, 1892. An example of the Fox type of truck especiallyadapted for locomotive tenders is found in United States Patent No.505,159, granted to S. Fox, September 19th, 1893, both of thesepatentsillustrating trucks in which the side frames are formed ofpressed steel.

Trucks of the Fox type are constructed with rigid side frames which attheir central portions support the transoms, the side framestransmitting the load from the transoms to the car axles through themedium of U shaped pedestals formed at the ends of the rigid sideframes, which pedestals rccch e and are supported by springs mounted onthe axle journal boxes, the legs of said pedestals also forn'iinghearings in which the journal boxes slide vertically. Sometimes the sidefran'ics of Fox trucks are built up of plates and commercial sections,an exam ple of such built-up side frame being found in United StatesPatent No. 553,431,granted to C. T. Schoen, January 21st, 1896.

Specification of Letters Patent.

Patented Jan. 16, 191. 7. Serial N 0. 68,525.

A specific object of thepresent invention is to so strengthen the sideframe of the Fox type of truck as to adapt it for use in railway rollingstock of increased capacity without materially increasing theproportions of the truck.

This invention is illustratedand described a in its adaptation for useas a freight car truck, but without special description it will bereadily appreciated that the improvements are equally applicable to alltrucks of the Fox or similar type when adapted for use in connectionwith locomotive tenders. Only so much of the Fox truck will be describedas is necessary to illus: trate this particular invention, referencesbeing had to the accompanying drawings in which like characters refer tolike parts,

Referring now in detail to the drawings,

1 indicates the side frame of what is known as the Fox type of truck,this side frame being similarin contour to the side frames illustratedA. the patents hereinbefore referred to. The plate forming the sideframe 1 is provided with an inwardly extending flange 2 extending alongthe top and end edge portions of the frame. To the inner side of the endportions of plate 1 auxiliary or reinforcing plates 3 are provided eachhaving an inwardly extending flange 4 adapted to contact with and besecured to the inwardly extending flange 2 of the side frame 1. Theseauxiliary or reinforcing plates may extend if desired throughout thewhole length of the side plate 1, but for the sake of illustration areshown in the drawings as only extending'from the ends of the side framesto points near the cross frame members or'transoms of the truck. Theinwardly extending flangev of the side frame 1 and also the inwardlyextending flanges of the reinforcing plates 2 extend continuously from apoint above the pedestal to the lower end portion of the pedestal leg,

frame plates 1 and 2 and extend in the opposite direction as far as itmay be considered desirable. These are secured together throughthemedium of the flanges 2 and in such a manner that there will be aspace 5 intervening between them, as shown in the drawings, either orboth of the plates being bent, as shown at 6 in Figs. 1 and 2, in such amanner as to bring them in contact with each other and be securedtogether by suitable means. The truck frame is provided with pedestalmembers 7 secured to the frame members in the manner shown in thedrawings and provided with pedestal braces or ties S. The pedestalmembers 7 are provided with a portion 9 projecting therefrom in such amanner as to fill up the width of the space 5 intervening between themembers 1 and 3, between which it is secured by rivets or other suitablemeans.

10 indicates the transoms or cross tie members of the truck frame, whichserve to tie together theframe members 1 forming the opposite sides ofthe truck, these transom members being braced and stiffened by the usualcross brace members 11 and the. center brace member 12. 13 indicates agusset member adapted to assist in securing together construction beingflanged in a vertical and bracing the transom members 10, the side framemembers 1 and the reinforcing members 3, these members being securedbetween the flanges 2 and 4 of the side frame and reinforcing members asillustrated in Fig. 4 of the drawings.

In the modified form of construction, as illustrated in Figs. 5 to r.inclusive, the flanges 15 on the upper and end portions of the sideframe members and the flanges 16 on the reinforcing members are made toeX- tend in a vertical and outward direction, and are secured togetherby rivets or other suitable means, the gusset member 17 in thisdirection in a suitable manner to contact with and be secured to theupwardly extending flanges of the side frame members and reinforcingmembers.

Further description of the essential parts of the FOX type of truck willbe. found in either of the aforementioned patents, and hence featureswhich are not pertinent to the present invention are not describedherein.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent is:
